Parquet Travis CI jobs to be turned off February 15th

Greetings Parquet PMC,

Infrastructure has reached out to you regarding the Travis CI Open Source policy changes, and the resulting need for Apache projects to migrate away from using Travis.

So far, we have received no response from your PMC.

On February 15th, we will begin the final phase of this migration, turning off Travis builds in order to bring our Travis usage down to 0.

We have found the following repositories mention or make use of .travis.yml files:

- parquet-mr.git
- parquet-cpp.git


You must immediately move to migrate your builds from Travis. If you do not, you will soon be unable to do builds that now rely on Travis.

Many projects have moved to using GitHub Actions, and migrating to GHA is quite straightforward. Other projects use Jenkins providing ARM support, with nodes using the arm label

If you are unsure how to proceed, I would be happy to explain your next steps.

Please at least respond to acknowledge the need to migrate away from Travis, and to tell us your current plans.

Thank you!

PARQUET-2502として参照されている移行ドキュメントから始め、parquet-mr.gitとparquet-cpp.gitの .travis.ymlファイルを調査してください。プロジェクトの移行計画を特定し、Travisベースのビルドを選択したサポート対象のCIに置き換えてください。Travisが不要になり、移行が認識されれば完了です。
